XmlBeans error: unexpected element CDATA when parsing String

I'm having problems parsing an xml string using XmlBeans. The problem itself is in a J2EE application where the string itself is received from external systems, but i replicated the problem in a small test project.

The only solution i found is to let XmlBeans parse a File instead of a String, but that's not an option in the J2EE application. Plus i really want to know what exactly the problem is because i want to solve it.

Source of test class:

public class TestXmlSpy {

    public static void main(String[] args) throws IOException {
        InputStreamReader reader = new InputStreamReader(new FileInputStream("d:\\temp\\IE734.xml"),"UTF-8");
        BufferedReader r = new BufferedReader(reader);
        String xml = "";
        String str;

        while ((str = r.readLine()) != null) {
            xml = xml + str;
        }
        xml = xml.trim();
        System.out.println("Ready reading XML");
        XmlOptions options = new XmlOptions();
        options.setCharacterEncoding("UTF-8");

        try {
            XmlObject xmlObject = XmlObject.Factory.parse(new File("D:\\temp\\IE734.xml"), options);
            System.out.println("Ready parsing File");
            XmlObject.Factory.parse(xml, options);
            System.out.println("Ready parsing String");
        } catch (XmlException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }   
}

The XML file validates perfectly against the XSD's im using. Also, parsing it as a File object works fine and gives me a parsed XmlObject to work with. However, parsing the xml-String gives the stacktrace below. I've checked the string itself in the debugger and don't really see anything wrong with it at first sight, especially not at row 1 column 1 where i think the Sax parser is having a problem with if i'm interpreting the error correctly.

This is an encoding problem, I used the below code that worked for me:

        File xmlFile = new File("./data/file.xml");
        FileDocument fileDoc = FileDocument.Factory.parse(xmlFile);
